Mechanical Engineer

THE MISSION ITERRA is building the system of record for low-altitude airspace. Above 400 feet, every aircraft is tracked, logged, and attributable. Transponders, flight plans, radar, ATC. Below it, nothing. No transponder mandate an adversary obeys, no log, no attribution. Every headline ends the same way: nobody could say what was in that airspace. A record-keeper cannot be a participant in the fight it is recording. That is why we are passive, and it is not a limitation, it is the product. WHAT WE ARE BUILDING Passive, edge-native RF and electro-optical sensing that autonomously detects and classifies Group 1-3 UAS without relying on pre-loaded signature libraries. Fused on the device. No active emissions. No cloud dependency. Purpose-built for denied, degraded, intermittent, and limited (DDIL) environments where legacy radar and library-dependent sensors fail. WHO WE ARE Small team. High trust. No bureaucracy. No tourists. Only builders. Field-tested, integrated with the command-and-control systems our customers already run, SDVOSB certified, and manufacturing on U.S. soil in Hatillo, Puerto Rico. WHAT YOU OWN The sensor is only as good as the box it lives in. You own the physical product: the enclosure, the radome, the mounts, the thermal path, the cable routing, and the drawings that let someone else build it again. You take a system that works on a bench in Hatillo and make it survive a mast in a tropical downpour, a vehicle roof on a dirt road, and a case thrown out of a truck. You report to the CTO and you are the mechanical owner of the product. Enclosure design in SolidWorks. Our current unit is a modular stack of sealed boxes on a tripod pole, one module per subsystem, designed to be built, opened, and serviced in the field. You inherit that design, fix what is wrong with it, and carry it to a production-ready revision. Top-down assemblies, sheet metal, machined 6061-T6, printed polymer, gaskets, heat-set inserts, radome windows. Thermal and structural analysis. An NVIDIA Jetson, multiple SDRs, LNAs, and a power board in a sealed enclosure in Caribbean heat. Hand calculations first, then ANSYS: steady-state and transient thermal, structural under load, shock, and vibration. You build the physical unit, instrument it, and report the temperature you measured next to the one you predicted. Waterproofing and environmental. IP65 baseline, IP67 where the customer demands it. Seal design, connector selection, drainage, condensation. Design to MIL-STD-810 profiles (temperature, humidity, salt fog, rain, vibration, shock), write the test plan, run what we can run in house, and specify what goes to a lab. Radome and RF transparency. Material selection for the antenna section: dielectric loss, UV, impact. You work with the RF engineer so the antenna that passed on the bench still passes inside the box. Radome loss is measured, not assumed. 3D printing, from prototype to production part. ASA for prototype runs,…
